Architect George Clarke takes on tiny spaces again, Ashley Walters tries to bond with his two sons in Truckers and Harold Finch goes missing in the return of Person Of Interest.

George Clarke’s Amazing Spaces, C4, 8pm
If tiny is your idea of perfectly formed where a bolthole, office or home is concerned, then this is the self-build show for you. Architect George Clarke runs his super-enthusiastic eye over a new set of projects, starting with an artist’s studio in the shape of an egg and an old ambulance being given a campervan makeover so it can sleep six (plus a dog). Clarke has to have his own project on the go at the same time, so he’s set himself the challenge of creating a tree house that’s accessible to all. Don’t look down.

Person Of Interest, Channel 5, 10pm
A welcome return for this offbeat futuristic drama starring Jim Caviezel as John Reese, the ‘professional’ who does the frontline crime prevention work for mastermind Harold Finch (Michael Emerson). But as season two boots up, Finch is missing, the victim of his own technological tracking creation that has been hacked by one of its previous targets. Will Reese have the brains to match his brawn in order to track down his brilliant puppet master?

No Sex Please, We’re Japanese, BBC2, 9pm
Beneath the slightly cheeky title of this documentary lurks a sad, disturbing tale. The Japanese birth rate is in freefall and dating is in sharp decline because an entire generation of Japanese men have been hooking up with virtual partners on the internet – that’s when they’re not indulging their passion for computer games and manga cartoons. Which leaves little time for engaging with living women. Hosted by Anita Rani.

Truckers, BBC1, 9pm
Top Boy star Ashley Walters steps to the fore to flesh out the character of Steven in this middle-of-the-road haulage drama. He’s seemed like a decent enough chap so far but tonight his promiscuous past catches up with him in the shape of his ex-wife and two sons. Cue a belated attempt at father-and-son bonding which reveals the softer side to a man used to giving it the full swagger behind the steering wheel.

Educating Yorkshire, C4, 9pm
All too soon it’s time for our final visit to Thornhill Community Academy, its inspiring teachers and endearingly wayward pupils. Tonight, it’s English teacher Mr Burton – a believer in sexy punctuation – in the spotlight. He’s trying to help struggling stammerer Musharaf, a Year 11 boy daunted by the prospect of the spoken section of an English exam. Will a spot of The King’s Speech provide the confidence Musharaf needs? And where to next? Cornwall? Glasgow? Norfolk?

Film: Everything Must Go, Film4, 9pm
Globally known and loved for playing Santa’s Elf, US comedy star Will Ferrell is in rarer serious drama mode here. Inspired by a Raymond Carver short story, this is the humane, melancholic portrait of Nick, an alcoholic salesman (Ferrell) who is fired from his job after falling off the wagon. He returns home to find his wife has moved out, changed the locks and dumped all his possessions outside. With his credit cards cancelled and nowhere to go, Nick decides to set up a car boot sale in his front garden – even though he no longer has a car. That this succeeds in being both funny and moving rests on a mature performance from Ferrell – a quiet revelation if you only know him from his zanier turns in the likes of Old School, Zoolander and Anchorman.

Film: Demolition Man, ITV4, 10.30pm
A pairing of Sandra Bullock and Sylvester Stallone may sound surreal today but it totally made sense 20 years ago in this superior sci-fi shoot-’em-up. Stallone is John Spartan, an LAPD cop whose nickname is the ‘demolition man’ for his non-softly softly approach to justice. Wesley Snipes is the psycho-baddie who proves to be his nemesis. The plot sees both men cryogenically frozen for being too violent for society to tolerate but they are thawed out in 2032 by dictator Dr Cocteau (Nigel Hawthorne) to discover a brave, new ultra-PC world. Poverty has been eradicated, along with sex and smoking, and former US presidents include Arnold Schwarzengger (not such a crazy thought now, eh?). Spartan partners up with Bullock, who plays a cop with a love of all things quaint and 20th-century.
